This is a great product at a great value. Our I.T. guy suggested that we purchase an Epson Artisan 837 and install the continuous ink system. He insisted that we would save money and that the ink would last a very long time before a refill was necessary. He was right on both accounts. Don't hesitate, buy now. The refill process is simple, and the print quality is great! CISinks is available for Live Support online and promptly answered my questions when I was placing my first order of ink. The ordering process is easy and the delivery is timely.
